dra7: Allow selecting a new dtb after board detection.
The DRA7 platforms requires that the dtb used in the SPL really matches the
platform to have the best MMC performances.
To detect the board type/version an I2C EEPROM is read. This requires that
DM is initialized before the detection. As a consequence we must reset the
DM after the board detection is a new dtb would better match the platform.
drivers: core: nullify gd->dm_root after dm_uninit()
To reset the DM after a new dtb is loaded, we need to call dm_uninit()
and then dm_init(). This fails however because gd->dm_root is not nullified
by dm_uninit().
Fixing it by setting gd->dm_root in dm_uninit().
drivers: core: Add the option SPL_DM_DEVICE_REMOVE to the Kconfig
It is currently not possible to include the support to remove devices in
the SPL. This is however needed by platforms that re-select their dtb after
DM is initialized; they need to remove all the previously bound devices
before triggering a scan of the new DT.
Add a Kconfig option to be able to include the support for device removal
in the SPL.
lib: fdtdec: Add function re-setup the fdt more effeciently
In some cases it may be useful to be able to change the fdt we have been
using and use another one instead. For example, the TI platforms uses an
EEPROM to store board information and, based on the type of board,
different dtbs are used by the SPL. When DM_I2C is used, a first dtb must
be used before the I2C is initialized and only then the final dtb can be
selected.
To speed up the process and reduce memory usage, introduce a new function
fdtdec_setup_best_match() that re-use the DTBs loaded in memory by
fdtdec_setup() to select the best match.
configs: dra7xx-evm: increase the size of the malloc's pool before relocation
This is required to take advantage of MULTI_DTB_FIT before relocation.
If it is too low, DM will be initialized only after relocation has
taken place. That is too late for the DRA7 because I2C DM is used before
the relocation to setup the voltages required, among other things, to
properly initialize the DRAM.
ti: remove usage of DM_I2C_COMPAT and don't disable DM_I2C in SPL
DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. The goal is to eventually remove DM_I2C_COMPAT
when all I2C "clients" have been migrated to use the DM API.
This a step in that direction for the TI based platforms.
Build tested with buildman:
buildman -dle am33xx ti omap3 omap4 omap5 davinci keystone
ti: common: board_detect: Allow DM I2C without CONFIG_DM_I2C_COMPAT
The EEPROM reading in the board detection code is done through legacy
I2C functions which on platforms using DM_I2C this functionality is
provided via the CONFIG_DM_I2C_COMPAT layer. To allow newer platforms
to use the board detection code without relying on CONFIG_DM_I2C_COMPAT
go ahead and add an I2C handling implementation that directly uses the
I2C DM functionality.

ARM: mvebu: a38x: sync ddr training code with mv_ddr-armada-18.09.02
This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-18.09 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.
Specifically this syncs with commit 99d772547314 ("Bump mv_ddr to
release armada-18.09.2").
The complete log of changes is best obtained from the mv-ddr-marvell.git
repository but some relevant highlights are:
The upstream code is incorporated omitting the portions not relevant to
Armada-38x and DDR3. After that a semi-automated step is used to drop
unused features with unifdef

sunxi: update README.sunxi64
Now that the Allwinner port in the official mainline ARM Trusted
Firmware repository has reached feature parity with the "legacy" ATF
port, let's use the opportunity to update the Allwinner 64-bit build
instructions. This changes:
- Update ATF build instructions to use the mainline repo.
- Add quick command lines for TL;DR people.
- Mention Allwinner H6 build target.
- Mention pre-built FEL binaries.

arm: sunxi: Reduce inrush current on Olimex OLinuXino-A20-Lime2-eMMC
The lime2 features a too large capacitor on the LDO3 output, which
causes the PMIC to shutdown when enabling power. To be able to still
boot up however, we must gradually enable power on LDO3 for this board.
We do this by enabling both the inrush quirk and the maximum slope the
AXP209 supports.

power: axp209: Limit inrush current for broken boards
Some boards feature a capacitance on LDO3's output that is too large,
causing inrush currents which as a result, shut down the AXP209. This
has been reported before, without knowing the actual cause.
A fix appeared to be done with
commit 0e6e34ac8dbb ("sunxi: Olimex A20 boards: Enable LDO3 and LDO4 regulators").
The description there is a bit misleading, the kernel does not hang
during AXP209 initialization, the PMIC shuts down, causing voltages to
drop and thus the whole system freezes.
While the AXP209 does have the ability to ramp up the voltage slowly, to
reduce these inrush currents, the voltage rate control (VRC) however is
not applicable when switching on the LDO3 output. Only when going from
an enabled lower voltage setting, to a higher voltage setting is the VRC
in effect.
To work around this problem, we set LDO3 to the lowest possible setting
of 0.7 V if it was not yet enabled, and then let the VRC (if enabled) do
its thing. It should be noted, that for some undocumented reason, there
is a short delay needed between setting the LDO3 voltage register and
enabling the power. One would expect that this delay ought to be just
after enabling the output power at 0.7 V, but this did not work.

power: axp209: Add support for voltage rate control on LDO3
The AXP209 LDO3 regulator supports voltage rate control, or can set a
slew rate.
This allows for the power to gradually rise up to the desired voltage,
instead of spiking up as fast as possible. Reason to have this can be
to reduce the inrush currents for example.
There are 3 slopes to choose from, the default, 'none' is a voltage rise
of 0.0167 V/uS, a 1.6 mV/uS and a 0.8 mV/uS voltage rise.
In ideal world (where vendors follow the recommended design guidelines)
this setting should not be enabled by default. Unless of course AXP209
crashes instead of reporting overcurrent condition as it normally should
do in this case.
